PSEUDOPOLYMOEPHINA HANZAWAI Cushman and Ozawa 



Plate 24, figures 1 a, b 



Pseudopolymorphina hanzawai Cushman and Ozawa, Contr. Cushman Lab. 

 Foram. Res., vol. 4, 1928, p. 16, pi. 1, fig. 15; Jap. Journ. Geol. Geogr., 

 vol. 6, 1929, p. 69, pi. 13, fig. 4; pi. 14, fig. 11; pi. 15, figs. 3, 4. 



Test large, about twice as long as broad, the later portion some- 

 what compressed and tending to become biserial in the last chambers, 

 greatest breadth above the middle, broadly rounded at the base; 

 chambers numerous, only slightly longer than broad, arranged in an 

 elongate, closed, sigmoid series becoming biserial; sutures distinct, 

 but very slightly depressed; wall thick, smooth, translucent; aper- 

 ture radiate, terminal. 



Measurements of the figured specimens: 2.25-2.40 mm.; breadth 

 1.10-1.26 mm.; thickness 0.85 mm. 



This species differs from Guitulina spicaeformis (Roemer) in its 

 biseral form in the adult and in the very much larger size. It is more 

 closely related to Guttulina yabei from which it is probably derived 

 by the addition of the biserial character. 



Distribution. — The types of this species are from the Pliocene of 

 Sawane, Island of Sado, Japan. It also occurs in the Pliocene of 

 Okuwa, Province of Kaga, Japan. We have somewhat similar 

 specimens from Albatross Station D2416 in 276 fathoms off the 

 Carolina coast and a single specimen which much resembles this 

 from the Miocene, Burdigalien moyen, of Le Coquillat, Leognan, 

 France.

 1897 (1899), p. 319, pi. 67, fig. 3. 



Test ovate (young) to fusiform (adult), obtuse at the base, acute 

 at the apertural end, slightly compressed; chambers nearly clavate, 

 not much overlapping, arranged in a nearly triserial series at the 

 start, becoming biserial later; sutures depressed, distinct; waU 

 smooth, thick; aperture radiate. 



Figured specimen, length 1.50 mm,; breadth 0.75 mm.; thickness 

 0,32 mm. 



Holotype.— (U. S. Nat. Mus. Coll. No. 20055.) From Albatross 

 dredgings off the eastern coast of the United States.
